Interface BindableId

All Superinterfaces:

Bindable

All Known Implementing Classes:

BindableIdEmbedded, BindableIdEmpty, BindableIdMap, BindableIdScalar

public interface BindableId
extends Bindable

Adds support for id creation for concatenated ids on intersection tables.

Specifically if the concatenated id object is null on insert this can be built from the matching ManyToOne associated beans. For example RoleUserId embeddedId object could be built from the associated Role and User beans.

This is only attempted if the id is null when it gets to the insert.

Method Detail

isEmpty

boolean isEmpty()

Return true if there is no Id properties at all.

isConcatenated

boolean isConcatenated()

Return true if this is a concatenated key.

getIdentityColumn

String getIdentityColumn()

Return the DB Column to use with genGeneratedKeys.

deriveConcatenatedId

boolean deriveConcatenatedId(PersistRequestBean<?> persist)

Create the concatenated id for inserts with PFK relationships.

Really only where there are ManyToOne assoc beans that make up the primary key and the values can be got from those.
